Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick connector technology, and in particular to a front-mounted quick connector for rapid insertion and installation. Background Technology
[0002] Quick-connect connectors, as a key electrical connection component, are widely used in industrial automation, especially in robots and automated production lines, where they facilitate the rapid connection of sensors, actuators, and controllers. Their core value lies in significantly reducing downtime during equipment assembly, commissioning, and maintenance, thereby improving overall production efficiency. While current quick-connect connector technology has achieved basic connection functions, there is still room for improvement in terms of reliability and ease of operation under complex working conditions.
[0003] In the prior art, patent CN219102343U proposes an angle connector with a rotating quick-connect fitting. This design incorporates a through-cavity structure within the angle connector body, with a quick-connect assembly in the front cavity and a 360-degree rotatable connecting nut in the rear cavity. This design solves the limitation of fixed connector orientation in narrow spaces by adjusting the direction of the quick-connect port through rotation, while simultaneously enabling rapid assembly of the connecting nut and the quick-connect body. While this type of structure has made progress in directional adaptability, significant drawbacks have been found in practical applications: First, the connection still relies on threaded tightening, requiring multiple turns of the nut to achieve a secure fit during installation, making the process cumbersome and time-consuming, especially in scenarios involving frequent disassembly and assembly, significantly increasing labor costs; Second, when the connecting wire is long, the tightening action can easily cause the wire to twist, increasing operational resistance and potentially leading to conductor fatigue or even insulation wear, posing electrical safety hazards; Third, threaded connections are prone to loosening under continuous vibration conditions, and vibrations caused by equipment operation and mechanical impacts are unavoidable in industrial environments. These structural defects directly lead to increased contact resistance, unstable signal transmission, and in severe cases, may cause equipment malfunctions.
[0004] The aforementioned technical contradictions are mainly manifested in the mismatch between the traditional rotary fastening mode and the demand for efficient and reliable connections. There is an urgent need to develop a quick-connect structure for fast installation and reliable locking, so as to fundamentally improve the engineering applicability of electrical connections. Utility Model Content
[0005] The technical problem to be solved by this utility model embodiment is how to provide a quick-install, lockable, and reliable front-plug quick-connect connector.
[0006] To address the aforementioned problems, this utility model provides a quick-connect front-mounted connector, comprising an angle connector, a plug, and a limiting mechanism. The angle connector includes a connecting tube and a sleeve at one end of the connecting tube. The limiting mechanism includes an elastic limiting component at the sleeve and a snap-fit component at the plug. The elastic limiting component includes an elastic element and a snap-fit head connected to the elastic element, the snap-fit head having a snap-fit groove. The snap-fit component includes a snap-fit cover and a snap-fit block on one side of the snap-fit cover. The plug is detachably inserted into the sleeve. During the insertion of the plug into the sleeve, the snap-fit block presses against the side wall of the snap-fit groove, causing the snap-fit head to rotate and twist the elastic element, thereby causing the snap-fit block to engage with the snap-fit groove.
[0007] A further technical solution is that the elastic limiting component further includes a sleeve, which is fixedly installed on the outside of the sleeve joint; an annular groove is formed on the inner side of the sleeve; and the elastic element is fixedly disposed in the annular groove.
[0008] A further technical solution is that the elastic limiting component also includes a twist cap, which is fixedly disposed on the outside of the card head.
[0009] A further technical solution is that the outer side of the twist cover is provided with multiple anti-slip protrusions at intervals.
[0010] A further technical solution is that the side wall of the card slot protrudes with a limiting block, the side of the card block is provided with a limiting groove, and the limiting block is embedded in the limiting groove.
[0011] A further technical solution is that the number of card blocks is multiple, and the multiple card blocks are arranged in a ring at intervals on one side of the card cover; the number of card slots is the same as the number of card blocks, and the multiple card slots are arranged in a ring at intervals on one side of the card head, and the multiple card blocks are engaged with the multiple card slots one by one.
[0012] A further technical solution is that the elastic element is a torsion spring.
[0013] A further technical solution is that the socket is provided with a limiting rod, the plug is provided with a limiting sleeve, and the limiting rod is inserted into the limiting sleeve.
[0014] A further technical solution is that there are multiple limiting rods, which are spaced apart within the sleeve; the number of limiting sleeves is the same as the number of limiting rods, which are spaced apart within the plug, and the multiple limiting rods are inserted into the multiple limiting sleeves one by one.
[0015] A further technical solution is that the angle connector is provided with a wire connector for connecting wires.
[0016] Compared with the prior art, the technical effects achieved by the embodiments of this utility model include:
[0017] This utility model provides a quick-connect front-mounted connector for rapid installation, including an angle connector, a plug, and a limiting mechanism. The angle connector includes a connecting tube and a sleeve at one end of the connecting tube. The limiting mechanism includes an elastic limiting component on the sleeve and a snap-fit component on the plug. The elastic limiting component includes an elastic element and a snap-fit head connected to the elastic element, with a snap-fit groove. The snap-fit component includes a snap-fit cover and a snap-fit block on one side of the snap-fit cover. The plug is detachably inserted into the sleeve. During the insertion of the plug into the sleeve, the snap-fit block presses against the side wall of the snap-fit groove, causing the snap-fit head to rotate and twist the elastic element, thus engaging the snap-fit block into the snap-fit groove. This utility model can automatically complete the snap-fit between the snap-fit block and the snap-fit groove during the insertion of the plug into the sleeve, achieving quick installation. Furthermore, the elasticity of the elastic element makes the snap-fit between the snap-fit block and the snap-fit groove more secure, avoiding snap-fit failure due to vibration or other factors.
[0018] The front-mounted quick-connect connector proposed in this utility model optimizes the connection mechanism of traditional quick-connect connectors through structural innovation. Its technical advantages are mainly reflected in three dimensions: installation efficiency, connection reliability, and anti-interference performance, as detailed below:
[0019] 1. Improved installation efficiency
[0020] By coordinating the elastic limiting component and the snap-fit component, during the insertion of the plug into the socket, the contact surface between the snap-fit block and the slot provides a guiding effect, forcing the snap-fit head to rotate along a preset path and compress the elastic element until the snap-fit block is fully embedded in the slot, at which point the elastic element automatically resets and locks in place. This process requires no manual intervention in rotation, achieving a "plug-and-lock" single-step installation mode, completely eliminating the multiple tightening actions of traditional threaded connections and significantly simplifying the operation process. Especially in industrial scenarios with frequent disassembly and assembly, it can greatly shorten equipment debugging and maintenance time and reduce the labor intensity of operators.
[0021] 2. Structural guarantee for connection stability
[0022] The preload design of the elastic element ensures that the locking block is always subjected to elastic clamping force after being embedded in the slot, forming a dynamic self-compensating contact interface. Compared to the static friction dependence of threaded connections, the elastic preload mechanism, through dynamic compensation, can maintain effective contact pressure under vibration or temperature change conditions, effectively suppressing the widening of the contact surface gap caused by material deformation and mechanical vibration. Furthermore, the geometric meshing structure of the slot and locking block replaces the traditional point contact mode with surface contact, dispersing stress distribution and avoiding structural fatigue caused by localized stress concentration, thereby extending the service life of the joint.
[0023] 3. Comprehensive optimization of torsional and vibration resistance
[0024] The axial, direct-insertion connection of the plug and socket fundamentally avoids the wire tangling problem caused by rotational installation. When the plug is inserted, the directional fit between the locking block and the slot restricts the circumferential freedom of the plug, ensuring that the wires only bear axial thrust rather than torsional force during the connection process. This prevents internal conductor damage or insulation layer breakage caused by torsional loads on long-distance wires. At the same time, the dynamic locking characteristic of the elastic limiting component can absorb the low-frequency vibration energy generated during equipment operation, suppressing the transmission of mechanical vibration to the wires through the connector and avoiding the risk of loosening due to long-term vibration.
[0025] 4. Structural compatibility and ease of maintenance
[0026] The resettable nature of the elastic element allows the connector to be repeatedly disassembled and reused. Wear on the slot and the block can be automatically compensated by the elastic clamping force, avoiding the problem of increased mating clearance caused by repeated insertion and removal.
[0027] In summary, this utility model systematically solves the technical contradictions of low installation efficiency, weak vibration resistance, and high maintenance costs of existing quick-connect couplings through mechanical structure innovation and mechanical property optimization, providing a solution for industrial automation equipment that combines rapid deployment and long-term stable connection.

As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.
[0040] See Figures 1-4 This utility model provides a quick-connect front-mounted connector with the advantages of fast installation and reliable locking. To achieve the above technical objectives, the quick-connect front-mounted connector includes an angle connector 1, a plug 2, and a limiting mechanism 6, the specific structure of which is described below:
[0041] The angle connector 1 includes a connecting pipe 3 and a sleeve 4 located at one end of the connecting pipe 3.
[0042] The limiting mechanism 6 includes an elastic limiting component 61 disposed on the socket 4 and a snap-fit component 62 disposed on the plug 2. The elastic limiting component 61 includes an elastic element 613 and a snap-fit head 614 connected to the elastic element 613. The snap-fit head 614 is provided with a snap-fit groove 622, and the number of snap-fit grooves 622 can be multiple. The snap-fit component 62 includes a snap-fit cover 621 and a snap-fit block 623 disposed on one side of the snap-fit cover 621. The number of snap-fit blocks 623 is the same as the number of snap-fit grooves 622, and there can also be multiple snap-fit blocks 623.
[0043] The plug 2 is detachably inserted into the socket 4 to achieve electrical connection between the plug 2 and the socket 4.
[0044] In this embodiment of the invention, during the process of inserting the plug 2 into the socket 4, the locking block 623 presses against the side wall of the slot 622, causing the locking head 614 to rotate and twist the elastic member 613, so that the locking block 623 is engaged in the slot 622 to form a locking connection. The elastic member 613 may specifically be a torsion spring.
[0045] Specifically, the upper side of the sidewall of the slot 622 is provided with an inclined surface. The card block 623 presses the inclined surface, causing the card head 614 to rotate and twist the elastic member 613. As the card block 623 gradually inserts into the slot 622, the elastic member 613 continuously stores energy. When the card block 623 is fully inserted into the slot 622 to form a snap, the elastic member 613 immediately resets and locks.
[0046] The front-mounted quick-connect connector proposed in this utility model optimizes the connection mechanism of traditional quick-connect connectors through structural innovation. Its technical advantages are mainly reflected in three dimensions: installation efficiency, connection reliability, and anti-interference performance, as detailed below:
[0047] 1. Improved installation efficiency
[0048] By coordinating the elastic limiting component 61 and the snap-fit component 62, during the insertion of the plug 2 into the socket 4, the contact surface between the snap-fit block 623 and the snap-fit groove 622 provides a guiding effect, forcing the snap-fit head 614 to rotate along a preset path and compress the elastic element 613 until the snap-fit block 623 is fully embedded in the snap-fit groove 622, at which point the elastic element 613 automatically resets and completes the locking. This process requires no manual intervention in the rotation operation, achieving a single-step installation mode of "insertion and locking," completely eliminating the multiple tightening actions of traditional threaded connections and significantly simplifying the operation process. Especially in industrial scenarios with frequent disassembly and assembly, it can greatly shorten equipment debugging and maintenance time and reduce the labor intensity of operators.
[0049] 2. Structural guarantee for connection stability
[0050] The preload design of the elastic element 613 ensures that the locking block 623 is always subjected to elastic clamping force after being embedded in the locking groove 622, forming a dynamic self-compensating contact interface. Compared to the static friction dependence of threaded connections, the elastic preload mechanism, through dynamic compensation, can maintain effective contact pressure under vibration or temperature change conditions, effectively suppressing the widening of the contact surface gap caused by material deformation and mechanical vibration. Furthermore, the geometric meshing structure of the locking groove 622 and the locking block 623 replaces the traditional point contact mode with surface contact, dispersing stress distribution and avoiding structural fatigue caused by local stress concentration, thereby extending the service life of the joint.
[0051] 3. Comprehensive optimization of torsional and vibration resistance
[0052] The axial insertion connection between plug 2 and socket 4 fundamentally avoids the wire tangling problem caused by rotational installation. When plug 2 is inserted, the directional engagement of the locking block 623 and the locking slot 622 constrains the circumferential freedom of plug 2, ensuring that the wire only bears axial thrust rather than torsional force during the connection process, preventing internal conductor damage or insulation layer breakage caused by torsional loads on long-distance wires. At the same time, the dynamic locking characteristic of the elastic limiting component 61 can absorb the low-frequency vibration energy generated during equipment operation, suppressing the transmission of mechanical vibration to the wire through the connector, and avoiding the risk of loosening due to long-term vibration.
[0053] 4. Structural compatibility and ease of maintenance
[0054] The resettable nature of the elastic element 613 allows the connector to be repeatedly disassembled and reused. The wear of the slot 622 and the block 623 can be automatically compensated by the elastic clamping force, avoiding the problem of increased mating clearance caused by repeated insertion and removal.
[0055] In summary, this utility model systematically solves the technical contradictions of low installation efficiency, weak vibration resistance, and high maintenance costs of existing quick-connect couplings through mechanical structure innovation and mechanical property optimization, providing a solution for industrial automation equipment that combines rapid deployment and long-term stable connection.
[0056] This utility model embodiment proposes a quick-connect front-mounted connector, including an angle connector 1, a plug 2, and a limiting mechanism 6. The angle connector 1 includes a connecting tube 3 and a sleeve 4 disposed at one end of the connecting tube 3. The limiting mechanism 6 includes an elastic limiting component 61 disposed at the sleeve 4 and a snap-fit component 62 disposed at the plug 2. The elastic limiting component 61 includes an elastic element 613 and a snap head 614 connected to the elastic element 613. The snap head 614 has a snap groove 622. The snap-fit component 62 includes a snap cover 621 and a snap block 623 disposed on one side of the snap cover 621. The plug 2 is detachably inserted into the sleeve 4. During the process of inserting the plug 2 into the sleeve 4, the snap block 623 presses against the side wall of the snap groove 622, causing the snap head 614 to rotate and twist the elastic element 613, so that the snap block 623 snaps into the snap groove 622 to form a snap-fit. This invention can automatically complete the engagement of the locking block 623 and the locking slot 622 during the process of inserting the plug 2 into the socket 4, thus achieving quick installation; and with the elastic force of the elastic element 613, the engagement between the locking block 623 and the locking slot 622 can be made more secure, avoiding engagement failure due to vibration or other factors.
[0057] Furthermore, in some preferred embodiments, the elastic limiting component 61 further includes a sleeve 611, which is fixedly installed on the outside of the sleeve joint 4; an annular groove 612 is provided on the inner side of the sleeve 611; and the elastic element 613 is fixedly disposed in the annular groove 612.
[0058] Specifically, the sleeve 611 can be installed on the outside of the socket joint 4 through a fastening hole and / or a snap-fit structure; this utility model is not specifically limited. The sleeve 611 is fixedly sleeved on the outside of the socket joint 4, providing reliable protection for the components inside the socket joint 4.
[0059] The elastic element 613 may specifically be a torsion spring. One end of the torsion spring is fixed to the inner wall of the annular groove 612, for example, by means of a fastening hole and / or a snap-fit structure, which is not specifically limited in this invention. The other end of the torsion spring is fixedly connected to the snap-fit head 614, for example, by means of a fastening hole and / or a snap-fit structure, which is not specifically limited in this invention.
[0060] Furthermore, the elastic limiting component 61 also includes a twist cap 615, which is fixedly disposed on the outside of the locking head 614. The outer side of the twist cap 615 is provided with a plurality of anti-slip protrusions 616 spaced apart. The twist cap 615 can be further rotatably connected to the sleeve 611, facilitating smooth rotation of the twist cap 615.
[0061] The locking head 614 can be rotated by the twist cap 615, causing the locking block 623 to disengage from the locking slot 622, thereby separating the angle connector 1 from the plug 2. The anti-slip protrusion 616 can be integrally formed with the twist cap 615.
[0062] The twist cap 615 allows operators to easily rotate the clip 614, improving disassembly efficiency. Multiple anti-slip protrusions 616 are fixedly arranged at equal intervals on the outer surface of the twist cap 615, providing operators with better leverage points when twisting the twist cap 615. Even with sweaty palms or a humid environment, the operator can apply force stably and accurately control the movement of the clip 614, facilitating the quick installation and removal of the plug 2 and ensuring a smooth installation and removal process.
[0063] Furthermore, the side wall of the slot 622 is provided with a limiting block 625, and the side of the card block 623 is provided with a limiting groove 626, and the limiting block 625 is embedded in the limiting groove 626.
[0064] Specifically, the locking block 623 engages inside the locking groove 622, and the limiting block 625 engages inside the limiting groove 626, forming an interlock. The locking block 623 can be a right-angled triangle, with its inclined surface corresponding to and fitting against the inclined surface of the limiting block 625. The limiting block 625 and the limiting groove 626 can be right-angled trapezoids to increase the contact area between them and improve the reliability of the engagement.
[0065] Furthermore, there are multiple card blocks 623, which are arranged in a ring at intervals on one side of the card cover 621; the number of card slots 622 is the same as the number of card blocks 623, which are arranged in a ring at intervals on one side of the card head 614, and the multiple card blocks 623 are engaged with the multiple card slots 622 one by one.
[0066] Specifically, the multiple locking blocks 623 arranged in a ring on the outer side of the cover 621 are mutually adapted to the multiple locking slots 622 arranged in a ring at equal intervals on the outer side of the head 614. When the plug 2 is inserted into the socket 4, the locking blocks 623 can be accurately inserted into the locking slots 622. At the same time, the limiting block 625 in the locking slot 622 and the limiting groove 626 of the locking block 623 are precisely matched to further strengthen the connection and prevent the plug 2 from loosening. The outer shape of the locking block 623 is a right-angled triangle, and its inclined surface is in contact with the inclined surface of the limiting block 625. During the insertion process, the inclined surface of the locking block 623 and the inclined surface of the side wall of the locking slot 622 form a guiding fit, guiding the locking block 623 to slide into the locking slot 622 along a preset path. The shapes of the limiting block 625 and the limiting groove 626 are right-angled trapezoids, which increases the contact area, improves the stability of the connection, and ensures that the plug 2 is stable and reliable during use, thereby ensuring stable current transmission.
[0067] Furthermore, in some preferred embodiments, the socket 4 is provided with a limiting rod 624, the plug 2 is provided with a limiting sleeve 627, and the limiting rod 624 is inserted into the limiting sleeve 627.
[0068] Specifically, there are multiple limiting rods 624, which are spaced apart within the socket 4 and can be arranged in a ring shape. The number of limiting sleeves 627 is the same as the number of limiting rods 624, and multiple limiting sleeves 627 are spaced apart within the plug 2 and can be arranged in a ring shape. Each limiting rod 624 is inserted into a corresponding limiting sleeve 627.
[0069] During the insertion of plug 2 into socket 4, limiting rod 624 and limiting sleeve 627 cooperate with each other. On the one hand, they can accurately limit the direction of plug 2 insertion, so that it enters socket 4 along a predetermined trajectory, avoiding plug 2 from deviating or tilting, and ensuring the accuracy of the connection. On the other hand, after plug 2 is installed, limiting sleeve 627 and limiting rod 624 are in close contact, which can effectively limit the rotation of plug 2 in socket 4. Elastic element 613 provides elasticity, which makes the locking block 623 stably inserted into the locking slot 622. At this time, even if it is subjected to external force pulling, vibration or other interference, plug 2 can be firmly in the predetermined position, ensuring the stability of electrical connection and maintaining stable current transmission.
[0070] Furthermore, in some preferred embodiments, the angle connector 1 is provided with a wire connector 5 for connecting wires.
[0071] Specifically, the bottom of the angle connector 1 is rotatably connected to a wire connector 5, which is a threaded connector. In actual connection operations, the threaded connector can be tightly screwed into the appropriate wire or equipment port for convenient and quick connection and installation.
[0072] Operating principle and advantages:
[0073] This invention, by configuring the plug 2 to cooperate with the angle connector 1, allows for simple insertion of the plug 2 directly into the socket 4 during actual use. At this point, the elastic limiting component 61 and the snap-fit component 62 interact. Specifically, the snap-fit block 623 smoothly inserts into the slot 622, its inclined surface abutting against the inclined surface of the limiting block 625. This contact process cleverly causes the snap-fit block 623 to rotate the snap-fit head 614, thereby twisting the elastic element 613 and creating suitable embedding space for the snap-fit block 623 and the limiting block 625. When the snap-fit block 623 is fully embedded in the slot 622, the elastic element 613 returns to its original position, and the limiting block 625 is also properly inserted. With the tight fit between the limiting block 625 and the limiting groove 626, and the locking block 623 and the locking slot 622, the plug 2 can be stably installed on the angle connector 1. In this way, the cumbersome rotation operation is completely eliminated when the angle connector 1 and the plug 2 are connected. The installation can be achieved quickly by simply plugging in, which greatly reduces the installation time. Moreover, the elastic component 613 always plays an elastic role throughout the installation process. Even if the wire vibrates, the stable locking structure between the locking block 623, the limiting block 625, the limiting groove 626 and the locking slot 622 can effectively prevent the wire from slipping and falling off, which strongly ensures the stability of the connector during use.
[0074] By setting a cooperative structure between the snap-fit component 62 and the elastic limiting component 61, when it is necessary to separate the plug 2 from the connector during use, the operator only needs to twist the cap 615 with equally spaced anti-slip protrusions 616 on the outside of the snap-fit head 614 to apply force steadily. The rotation of the cap 615 will cause the snap-fit head 614 to rotate, which in turn will cause the snap-fit block 623 to move, so that the limiting block 625 at the end of the snap-fit block 623 will disengage from the limiting groove 626. At this time, the right-angled side of the inner side of the limiting groove 626 and the right-angled side of the limiting block 625 are offset from each other, and the snap-fit block 623 can be smoothly pulled out from the slot 622, and the plug 2 will be removed. The whole disassembly process is quick and smooth.
[0075] Furthermore, during installation, the limiting rod 624 is inserted into the inner side of the limiting sleeve 627, precisely restricting the rotation of the plug 2 and ensuring that the elastic force of the elastic element acts stably on the locking block 623 and the limiting block 625, thereby comprehensively improving the overall installation stability.
